The development of sustainable processes for the recycling of plastic is a major environmental issue to reduce the pollution by this kind of waste. The electro-oxidation of plastic wastes in electrolysers powered by renewable energies is a promising option to produce hydrogen at low temperature while diminishing the energy demand compared to Oxygen...

The production of H2 via electrolysis seems to be the best alternative to traditional catalytic reforming processes. The electrolysis of lignin allows to produce pure H2 while valorizing a low-price biomass waste with (theoretically) lower energy requirements than water electrolysis. Previous studies were published in the last years dealing with th...

Hydrogen production by the electrolysis of plastic-waste was recently suggested as an alternative approach to water electrolysis, owing to its favoured thermodynamics. However, the fundamental aspects of such electro-catalytic process were not studied in detail. Here we propose a new approach to understand the electrolysis of polymers, by the use o...

Novel carbon-MgCl2 composites were designed as robust ammonia carriers for selective catalytic reduction (SCR) system, with graphite (Gt) and graphene nanoplatelets aggregates (GNA) as additives to MgCl2. The cylindrically pelletized composites manifested high structural stability above the melting temperature of MgCl2 with 95 % mass retention, whe...

A thorough study of the Y1-XZrxMnO3+δ series is presented with the objective to use those materials as SOFC cathode. These pure and Zr-doped yttrium manganites exhibit a layered hexagonal structure associated to a peculiar 5-fold bi-pyramidal coordination of manganese that makes it intrinsically different from the traditional cubic-like perovskite...
